An image alt tag (also known as an "alt attribute" or "alt description") is a HTML attribute that provides a textual description of an image on a web page. The alt tag is intended to provide a description of the image for users who are unable to see the image, such as visually impaired users who are using a screen reader, or users who have slow internet connections and the image has not yet loaded.
The importance of the alt tag lies in its accessibility and SEO benefits. For visually impaired users, the alt tag provides information about the image that they would otherwise not be able to see. This can greatly improve the accessibility of your website and make it easier for everyone to access and understand your content.
In addition to accessibility, the alt tag is also important for SEO. Search engines use the alt tag to understand the content and context of an image, which can help to improve the search engine ranking of your website. When you provide a descriptive and relevant alt tag, it helps search engines understand the content of the image and can lead to better search engine visibility for your website.
In conclusion, using descriptive and relevant alt tags is important for both accessibility and SEO. By providing a textual description of images on your website, you can improve the user experience for visually impaired users and also improve the search engine visibility of your website.
